1. Analysis of Al2O3-ZrO2 ceramic insert in turning process of Ti-6Al-4V alloy using grey Taguchi-based response surface methodology (GT-RSM)
Abstract The present investigation aimed at a sustainable green turning operation of Ti-6Al-4V alloy using multi-objective optimization of surface roughness, tool flank wear, material removal rate, and tool wear loss with cutting speed, feed rate, and depth of cut as input parameters. The experiments were performed on a CNC lathe machine using an alumina-zir

2. MORPHOGENIC AND STRUCTURAL CHARACTERISTICS OF MARANDU GRASS AFFECTED BY FERTIGATION WITH TREATED SEWAGE EFFLUENT AND CUTTING HEIGHT
ABSTRACT The response of biomass flow components of forage from the interaction between fertigation with wastewater and cutting height during the year is little known. The objective of this work was to verify the responses of morphogenic and structural characteristics of Urochloa brizantha as a function of fertigation application strategies with sewage treat

3. ARTIFICIAL NEURAL NETWORKS FOR PREDICTION OF PHYSIOLOGICAL AND PRODUCTIVE VARIABLES OF BROILERS
ABSTRACT Due to a number of factors involving the thermal environment of a broiler cutting installation and its interaction with the physiological and productive responses of birds, artificial intelligence has been shown to be an interesting methodology to assist in the decision-making process. For this reason, the main aim of this work was to develop an art

4. MINI-CUTTING TECHNIQUE FOR VEGETATIVE PROPAGATION OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagati

5. Avaliação de desvio dimensional em Inconel 718 após a retificação em diferentes técnicas de lubri-refrigeração
RESUMO O Inconel 718 é uma liga à base de níquel que possui elevada resistência à fadiga e à fluência, ductilidade, rigidez, inércia química e capacidade de operar em elevadas temperaturas, por isto é bastante utilizada na fabricação de peças aeronáuticas de alto rendimento. Estas peças exigem tolerâncias dimensionais e geométricas estreitas

7. SOLAR RADIATION USE EFFICIENCY AND GROSS PROTEIN OF SORGHUM FORAGE ARE MODIFIED BY THE CUTTING MANAGEMENT
Resumo O objetivo deste trabalho foi determinar o crescimento, a eficiência do uso da radiação solar e a proteína bruta do sorgo forrageiro submetido a diferentes manejos de cortes. Foi utilizado um esquema unifatorial em delineamento de blocos casualizados (manejo de cortes), que variou do tratamento sem corte até quatro cortes. O primeiro corte ocorre

8. Weeds in a Sugar Cane Soil Cultivated with Crotalaria juncea
RESUMO: As culturas de cobertura desempenham um papel importante na agricultura sustentável, uma vez que reduzem a erosão do solo, favorecem a incorporação de nitrogênio por este e reduzem ou modificam a comunidade de ervas daninhas. A fim de avaliar as mudanças relacionadas ao cultivo e à incorporação de crotalária (Crotalaria juncea L.1753) na co

9. On the Machinability and Surface Finish of Superalloy GH909 Under Dry Cutting Conditions
GH 909 alloy is a kind of low thermal expansion superalloy with high strength and low expansion coefficient. It is mainly used for manufacturing of aero-engine turbine casings, sealing ring, vanes and other gap control parts, to improve the working efficiency and thrust of the engine as well as to reduce gas loss and fuel consumption. However, the machinabil

10. The use of crude glycerin as an alternative to reduce fermentation losses and enhance the nutritional value of Piatã grass silage
ABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutti

11. Investigation of High-Speed Cryogenic Machining Based on Finite Element Approach
Abstract The simulation of cryogenic machining process because of using a three-dimensional model and high process duration time in the finite element method, have been studied rarely. In this study, to overcome this limitation, a 2.5D finite element model using the commercial finite element software ABAQUS has been developed for the cryogenic machining proc

12. Physicochemical and functional characteristics of residual pulp of potato
Abstract Starch-rich liquid effluent is generated after peeling, cutting and washing of tubers during the fries processing. After sedimentation of this effluent is recovered a wet residual pulp, and after drying is obtained dry residual pulp or simply named in this study residual pulp of potato (RPP). In order to convert the effluent into a material easy to
